Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a device for detecting the verticality of the inner hole of an oil passage cover. Background Technology

[0002] The oil passage cover is an end cover on the stator and rotor of a new energy drive motor, serving to cool the motor and reduce noise. The oil passage cover inner hole perpendicularity detection device is a special equipment used to accurately measure the perpendicularity error between the axis of the inner hole of the oil passage cover and the end face. It fixes the workpiece and calibrates the benchmark through a mechanical positioning system, and collects data from multiple cross-sections of the inner hole using high-precision sensors (such as electronic level, laser rangefinder or dial indicator). After calculation and analysis, the perpendicularity deviation value is obtained, thereby quickly determining whether the workpiece meets the design requirements. It is widely used in the quality control of precision parts in hydraulic systems, automobile manufacturing and other fields.

[0003] In practical applications, existing oil cover plate inner hole perpendicularity testing devices often suffer from poor contact due to surface wear, oil stains, or other issues with the fixture or positioning reference. This can lead to slight displacement or tilting of the workpiece after clamping, affecting the stability of the perpendicularity measurement reference. Furthermore, if the measurement reference is not strictly aligned with the inner hole axis, the perpendicularity error can be abnormally amplified or concealed, ultimately resulting in distorted measurement data and errors in the workpiece's machining accuracy.

[0004] Therefore, a device for detecting the verticality of the inner hole of an oil passage cover is needed to improve the above-mentioned problem. Utility Model Content

[0005] To address the problem that in practical applications of perpendicularity testing devices for oil cover plate inner hole perpendicularity testing, poor contact due to surface wear or oil contamination of the fixture or positioning reference can lead to slight displacement or tilting of the workpiece after clamping, thus affecting the stability of the perpendicularity measurement reference, this utility model provides an oil cover plate inner hole perpendicularity testing device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for detecting the verticality of the inner hole of an oil vent cover includes a mounting frame, a fixing plate mounted on the inner wall of the mounting frame, a verticality detection component mounted on the bottom outer wall of the fixing plate, a mounting plate mounted directly below the fixing plate and on the side wall of the mounting frame, a fixing clamping component mounted on the outer wall of the mounting plate, and a controller mounted on the side wall of the mounting frame.

[0008] The verticality detection component includes a fixed base, which is embedded in the bottom outer wall of a fixed plate. A fixing block is installed on the outer wall of the fixed base, wherein multiple fixing blocks are provided and are respectively located on the bottom outer wall of the fixed base. A cross shaft I is installed on the inner wall of the fixing block. An electric cylinder is rotatably connected to the outer wall of the cross shaft I. One end of the electric cylinder is rotatably connected to a cross shaft II. A connecting block is rotatably connected to the outer wall of the cross shaft II. A sensor fixing seat is installed on the outer wall of the connecting block.

[0009] As a preferred embodiment of this utility model, the connecting blocks are provided in multiple sets and are respectively located on the outer wall of the sensor fixing base. An mounting bracket is installed on the inner wall of the sensor fixing base, and a verticality detection sensor is installed on the inner wall of the mounting bracket.

[0010] As a preferred embodiment of this utility model, a ranging sensor is installed on one side of the mounting bracket and on the bottom outer wall of the sensor mounting base. Multiple sets of ranging sensors are provided and are respectively located on the bottom outer wall of the sensor mounting base, and the ranging sensors are in a ring structure.

[0011] As a preferred embodiment of this utility model, the fixing and clamping assembly includes a pneumatic chuck, which is embedded in the outer wall of the mounting plate and located directly below the sensor fixing seat. A limit plate is provided on the inner wall of the pneumatic chuck, and a fixing shell is provided on the outer wall of the gripper of the pneumatic chuck.

[0012] As a preferred embodiment of this utility model, an elastic contact sensor is embedded in the inner wall of the fixed housing, and a micro motor is installed on one side of the elastic contact sensor and on the inner wall of the fixed housing. The drive shaft of the micro motor is equipped with a threaded rod, and one end of the threaded rod is threadedly connected to a sleeve.

[0013] As a preferred embodiment of this utility model, a pressing clamping block is installed on the outer wall of the sleeve, a sliding rod is slidably connected to the outer wall of the pressing clamping block, a fixed base plate is slidably connected to the outer wall of the sliding rod, and the fixed base plate is installed on the side wall of the fixed housing. The sliding rod is provided in two sets and is located on the outer wall of the pressing clamping block respectively.

[0014] As a preferred embodiment of this utility model, the controller is connected to an electric cylinder, a verticality detection sensor, a distance sensor, a pneumatic chuck, an elastic contact sensor, and a micro motor via wires, and the connection method is electrical connection.

[0015] As a preferred embodiment of this utility model, the ranging sensor is located directly above the pneumatic chuck, the fixed housing is provided with multiple sets and is respectively located on the outer wall of the gripper of the pneumatic chuck, and the pressing clamping block is located directly above the fixed housing.

[0016] Compared with the prior art, this utility model, by setting a fixed clamping component in the oil vent cover plate inner hole verticality detection device, can achieve downward pressure on the oil vent cover plate workpiece, while the pneumatic chuck clamps and fixes the oil vent cover plate workpiece inward. After the oil vent cover plate workpiece is placed in the clamping cavity of the pneumatic chuck, the controller is activated to drive the pneumatic chuck's jaws to perform the clamping action. When the elastic contact sensor generates an electrical signal due to contact with the workpiece, it is transmitted to the controller via a wire. When the signal strength reaches a preset threshold, the controller drives the micro motor to rotate, and its drive shaft drives the threaded rod to rotate. The rotation pushes the sleeve downward along the axis, causing the pressing clamping block to move synchronously downward along the outer wall of the slide rod. The pressing clamping block presses and fixes the oil vent cover plate workpiece to the pneumatic chuck base surface. At the same time, the pneumatic chuck jaws move centripetally to complete the outer circle positioning of the workpiece, forming a composite clamping mode of axial pressing and radial clamping. This solves the problem that in the practical application of existing oil vent cover plate inner hole verticality detection devices, poor contact due to surface wear, oil stains, etc. on the fixture or positioning reference often leads to slight displacement or tilting of the workpiece after clamping, which in turn affects the stability of the verticality measurement reference.

[0017] This invention, by setting a perpendicularity detection component in the perpendicularity detection device of the inner hole of an oil vent cover, enables the adjustment of the sensor fixing seat position based on the end face distance of the inner hole of the oil vent cover, so that the measurement reference of the perpendicularity detection sensor is aligned with the axis of the inner hole. After the oil vent cover workpiece is fixed, the controller drives the distance sensor to run synchronously. The distance sensor acquires the distance data of the end face of the inner hole of the oil vent cover through multi-point distance measurement, and converts the measured value into an electrical signal, which is transmitted to the controller via a wire. The controller controls the coordinated action of the electric cylinder based on the end face distance data. The electric cylinder drives the cross shaft and the connecting block to rotate, driving the sensor fixing seat to perform precise displacement adjustment until the end face of the sensor fixing seat is completely flush with the inner hole of the oil vent cover, achieving precise alignment of the measurement reference of the perpendicularity detection sensor with the axis of the inner hole. At this time, the perpendicularity detection sensor collects data in real time and transmits it to the controller, thereby solving the problem that if the measurement reference and the axis of the inner hole are not strictly aligned, the perpendicularity error will be abnormally amplified or hidden, ultimately causing the measurement data to be distorted and the machining accuracy of the workpiece to be incorrect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] In this embodiment, specific references Figure 1 , Figure 2 and Figure 3The verticality detection component 3 includes a fixed base 301, which is embedded in the bottom outer wall of the fixed plate 2. Fixed blocks 302 are installed on the outer wall of the fixed base 301. Multiple sets of fixed blocks 302 are arranged on the bottom outer wall of the fixed base 301. A first cross shaft 303 is installed on the inner wall of the fixed block 302. An electrically controlled cylinder 304 is rotatably connected to the outer wall of the first cross shaft 303. One end of the electrically controlled cylinder 304 is rotatably connected to a second cross shaft 305. A connecting block 306 is rotatably connected to the outer wall of the second cross shaft 305. A sensor mounting base 307 is installed on the outer wall of block 306. Multiple sets of connecting blocks 306 are provided and are located on the outer wall of sensor mounting base 307. A mounting bracket 308 is installed on the inner wall of sensor mounting base 307. A verticality detection sensor 309 is installed on the inner wall of mounting bracket 308. A ranging sensor 310 is installed on one side of mounting bracket 308 and on the bottom outer wall of sensor mounting base 307. Multiple sets of ranging sensors 310 are provided and are located on the bottom outer wall of sensor mounting base 307. The ranging sensors 310 are in a ring structure.

[0027] In this embodiment, specific references Figure 1 , Figure 2 , Figure 4 and Figure 5 The clamping assembly 5 includes a pneumatic chuck 501, which is embedded in the outer wall of the mounting plate 4 and located directly below the sensor mounting base 307. A limit plate 502 is provided on the inner wall of the pneumatic chuck 501. A fixing housing 503 is provided on the outer wall of the grippers of the pneumatic chuck 501. An elastic contact sensor 504 is embedded in the inner wall of the fixing housing 503. A [missing information - likely a device or component] is installed on one side of the elastic contact sensor 504 and on the inner wall of the fixing housing 503. A micro motor 505 has a drive shaft with a threaded rod 506. One end of the threaded rod 506 is threadedly connected to a sleeve 507. A pressing clamping block 508 is installed on the outer wall of the sleeve 507. A sliding rod 509 is slidably connected to the outer wall of the pressing clamping block 508. A fixed base plate 510 is slidably connected to the outer wall of the sliding rod 509. The fixed base plate 510 is installed on the side wall of the fixed housing 503. There are two sets of sliding rods 509, which are located on the outer wall of the pressing clamping block 508 respectively.

[0028] The controller 6 is electrically connected to the electric cylinder 304, verticality detection sensor 309, distance sensor 310, pneumatic chuck 501, elastic contact sensor 504 and micro motor 505 via wires, which powers the device. The distance sensor 310 is located directly above the pneumatic chuck 501. The fixed housing 503 is provided with multiple sets of clamps located on the outer wall of the grippers of the pneumatic chuck 501. The pressing clamping block 508 is located directly above the fixed housing 503.

[0029] When the verticality detection device for the inner hole of the oil cover plate in this solution is working, the controller 6 is connected to the electric cylinder 304, verticality detection sensor 309, distance sensor 310, pneumatic chuck 501, elastic contact sensor 504 and micro motor 505 through wires, and the connection is electrically connected. This makes the device powered on, and then the controller 6 controls the electric cylinder 304, verticality detection sensor 309, distance sensor 310, pneumatic chuck 501, elastic contact sensor 504 and micro motor 505 to operate.

[0030] By placing the oil vent cover workpiece on the inner wall of the pneumatic chuck 501, and then turning on the controller 6, the controller 6 controls the pneumatic chuck 501 to operate, thereby causing the jaws of the pneumatic chuck 501 to clamp the oil vent cover workpiece. When the fixed housing 503 is in contact with the oil vent cover workpiece, the oil vent cover workpiece and the elastic contact sensor 504 come into contact, causing the elastic contact sensor 504 to generate an electrical signal, which is transmitted to the controller 6 through a wire. When the set parameters are reached, the controller 6 controls the micro motor 505 to operate. The drive shaft of the micro motor 505 drives the threaded rod 506 to rotate, thereby causing one end of the threaded rod 506 to drive the sleeve 507 to move downward through the threaded connection. This causes the sleeve 507 to move the pressing clamping block 508 downwards. The pressing clamping block 508 moves downwards on the outer wall of the slide rod 509, thereby causing multiple sets of pressing clamping blocks 508 to press down on the oil passage cover plate workpiece simultaneously. This makes the pressing oil passage cover plate workpiece adhere to the base surface of the pneumatic chuck 501. At the same time, as the pneumatic chuck 501 further adheres to the outer wall of the oil passage cover plate workpiece for clamping and fixing, the stability of the oil passage cover plate workpiece is better when clamped. This solves the problem that in the actual application of existing oil passage cover plate inner hole verticality detection devices, poor contact due to surface wear, oil stains, etc. of the fixture or positioning reference often leads to slight displacement or tilting of the workpiece after clamping, which affects the stability of the verticality measurement reference.

[0031] A mounting bracket 308 is installed on the inner wall of the sensor mounting base 307. A verticality detection sensor 309 is installed on the inner wall of the mounting bracket 308. A distance measuring sensor 310 is installed on one side of the mounting bracket 308, located on the bottom outer wall of the sensor mounting base 307. Multiple distance measuring sensors 310 are arranged, each located on the bottom outer wall of the sensor mounting base 307, forming a ring structure. When the oil vent cover is fixed, the switch of the controller 6 is turned on, causing the controller 6 to control the operation of the distance measuring sensors 310. Since multiple distance measuring sensors 310 are arranged, they measure the distance to the end face of the inner orifice of the oil vent cover. The distance measuring sensors 310 then generate data based on this distance, which in turn generates an electrical signal that is transmitted to the controller 6 via a wire. The controller 6 then uses this data to determine the distance to the end face of the inner orifice of the oil vent cover. The system operates so that the controller 6 controls the electric cylinder 304 to operate. Since there are multiple sets of electric cylinders 304, the operation of electric cylinders 304 at different positions causes one end of the electric cylinder 304 to move the sensor mounting base 307 through the cross shaft 305 and the connecting block 306, thereby adjusting the position of the sensor mounting base 307 so that the end face of the sensor mounting base 307 and the inner hole of the oil cover plate are flush with each other. This aligns the measuring reference of the perpendicularity detection sensor 309 with the axis of the inner hole. Subsequently, the perpendicularity detection sensor 309 generates an electrical signal, which is transmitted to the controller 6 through the wire. The controller 6 displays the perpendicularity value of the inner hole of the oil cover plate in real time for the operator to observe. This solves the problem that if the measuring reference and the axis of the inner hole are not strictly aligned, the perpendicularity error will be abnormally amplified or hidden, ultimately causing the measurement data to be distorted and the machining accuracy of the workpiece to be incorrect.

[0032] The controller 6, electric cylinder 304, verticality detection sensor 309, distance sensor 310, pneumatic chuck 501, elastic contact sensor 504, and micro motor 505 used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the controller 6, electric cylinder 304, verticality detection sensor 309, distance sensor 310, pneumatic chuck 501, elastic contact sensor 504, and micro motor 505 will not be described in detail here.
